Abstract

An investigation into an outbreak of Salmonella Newport infections in Canada was initiated in July 2020. Cases were identified across several provinces through whole-genome sequencing (WGS). Exposure data were gathered through case interviews. Traceback investigations were conducted using receipts, invoices, import documentation, and menus. A total of 515 cases were identified in seven provinces, related by 0-6 whole-genome multi-locus sequence typing (wgMLST) allele differences. The median age of cases was 40 (range 1-100), 54% were female, 19% were hospitalized, and three deaths were reported. Forty-eight location-specific case sub-clusters were identified in restaurants, grocery stores, and congregate living facilities. Of the 414 cases with exposure information available, 71% (295) had reported eating onions the week prior to becoming ill, and 80% of those cases who reported eating onions, reported red onion specifically. The traceback investigation identified red onions from Grower A in California, USA, as the likely source of the outbreak, and the first of many food recall warnings was issued on 30 July 2020. Salmonella was not detected in any tested food or environmental samples. This paper summarizes the collaborative efforts undertaken to investigate and control the largest Salmonella outbreak in Canada in over 20 years.

多省爆发与红洋葱有关的纽波特沙门氏菌感染:加拿大 20 多年来最大一次沙门氏菌疫情报告。
2020 年 7 月,加拿大开始对纽波特沙门氏菌感染疫情进行调查。通过全基因组测序(WGS)确定了多个省份的病例。通过病例访谈收集暴露数据。利用收据、发票、进口文件和菜单进行了溯源调查。在七个省份共发现了 515 个病例,这些病例之间存在 0-6 个全基因组多焦点序列分型(wgMLST)等位基因差异。病例的中位年龄为 40 岁(1-100 岁不等),54% 为女性,19% 曾住院治疗,有 3 例死亡病例。在餐馆、杂货店和集体生活设施中发现了 48 个特定地点病例亚群。在有接触信息的 414 例病例中,71%(295 例)报告在发病前一周吃过洋葱,而在报告吃过洋葱的病例中,有 80% 特别报告吃过红洋葱。溯源调查发现,来自美国加利福尼亚州种植者 A 的红洋葱可能是此次疫情的源头,并于 2020 年 7 月 30 日发布了众多食品召回警告中的第一个。在所有检测的食品或环境样本中均未检测到沙门氏菌。本文总结了为调查和控制加拿大 20 多年来最大的沙门氏菌疫情而开展的合作。

期刊介绍: Epidemiology & Infection publishes original reports and reviews on all aspects of infection in humans and animals. Particular emphasis is given to the epidemiology, prevention and control of infectious diseases. The scope covers the zoonoses, outbreaks, food hygiene, vaccine studies, statistics and the clinical, social and public-health aspects of infectious disease, as well as some tropical infections. It has become the key international periodical in which to find the latest reports on recently discovered infections and new technology. For those concerned with policy and planning for the control of infections, the papers on mathematical modelling of epidemics caused by historical, current and emergent infections are of particular value.
